The high school SCP-XXXX was first identified in is to be watched for further anomalous activity until ██/██/██.

I would object to censoring the date here. How would agents know when to stop operations? This could represent potential waste in resources if they just end up spying on a particular school for decades.

12th grade physics teacher

Is it always 12th grade? What about people who don't have a concept of "12th grade"? Such as myself, since Singapore has no "12th grade" (our closest equivalent would be Junior College Year 2) and I know a lot of people who never went to Junior College and went straight to polytechnics. How will they perceive such a being as?

It had been agreed upon before the interview that Mr. ████ would only be referred to with pronouns or as "Mr. Man". This was to avoid spread of SCP-XXXX.

"Mr. Man" seems odd for a placeholder name. Also, won't the interviewer be affected when the infected interviewee mentions the teacher's name?

Hmm… this is delightfully whimsical and that actually got me to write a little review about it (despite the late hours I'm writing from). The interview seems interesting. However, I feel that it could be better if we see multiple interviews with the same infected D-class to show the arbitrariness of the memory alterations and their inconsistencies (instead of just mentioning it in a footnote).

The teacher knowing the Foundation and "willing" to cooperate with it is a nice touch, IMO.

That had somehow slipped my mind. Fixed.

Is it always 12th grade?

I'm not sure. I'm thinking either a) it isn't and it's just whatever is the closest equivalent, or b) it always is, and what the person's background is becomes irrelevant as their memories are overwritten and changed.

I agree that it's an odd placeholder, and I'll need to change it. The idea though is that it's there in the first place to prevent the interviewer from getting infected.

I'll be adding some more interviews too, which should expand on the idea, and maybe elaborate on Mr. ████'s current state (which is pretty much some kind of hell, as it's heavily implied that this infection is against his will).

SCP-XXXX progressively worsens over time, as the affected person's memories are altered (or entirely replaced) to include Mr. ████.

Affected person should say host.

Memories of significant events in the affected person's life may be rewritten or replaced entirely by a new memory. However, these memories are always altered or replaced to include Mr. ████.

Way too redundant, get rid of it.

Children make up names all the time. Some kid could randomly say it on accident, and then have memories of the 12th grade when he's in the fourth. There's also the possibility that there are other people with the last name as Mr. ████, so this thing should spread like wildfire, people telling therapists about the 12th grade teacher named ████ that they never had, and then him telling his wife, and she telling her friends, and eventually an entire country had the same 12th grade physics teacher. Make it more difficult to be "contracted, " because this idea is way too volatile.
